Adequate process modeling is one of the key factors for the success of software organizations. Currently, organizations face with a very high competition and consequently they have to continuously improve their processes. This improvement could require changes of the process models so it is important to evaluate the maintainability of these models to facilitate their evolution. In this paper we present the results obtained with the replication of an experiment to validate a set of metrics for software process models (SPMs). The replicas were performed at the Italian Universities of Sannio (Italy) and Federico II (Naples). They are part of a family of experiments and have confirmed the results obtained in the original experiment carried out at the University of Castilla-La Mancha (Spain). As a result a set of useful indicators of the understandability and modifiability of the SPMs, which are two key sub-characteristics of their maintainability, have been obtained.

There has been an increasing interest in integrating decision support systems (DSS) and expert systems (ES) to provide decision makers a more accessible, productive and domain-independent information and computing environment. This paper is aimed at designing a multiple expert systems integrated dec...

In this paper, an evolving system is introduced. That any system is evolving means that any entity in the system is in developing state and entities compete with each other. Any entity can be represented by development of the entity and its environment consisting of a closed cycle. Any subsystem is ...

Traditional data envelopment analysis (DEA) theory assumes that decision variables are regarded as inputs or outputs, and no variable can play the roles of both an input and an output at the same time. In fact, there exist some variables that work as inputs and outputs simultaneously and are called ...

Due to pressures from both energy and environment, electric vehicles (EVs) and their related technologies have experienced considerable achievements in China in recent years. This paper firstly presents the EV development status in China with key statistics including EV market status, mainstream tec...
